Title: Improvements in or relating to a method for improving the strength of artificial insolubilised protein filaments
IPC: D01F4/00
Filed: 1948-03-03
Abstract: Artificial protein filaments which have been rendered insoluble by treatment with saline solutions adapted to form monomeric thioformaldehyde or the trimer thereof in situ, these solutions containing formaldehyde or a compound which will yield formaldehyde under the conditions of the treatment, a salt of a reducing sulphur acid in which the atomic proportion reckoned on the anhydrous salt of oxygen, if present, to sulphur, does not exceed 2 : 1, and an acid which does not oxidize the salt of the sulphur acid and which is completely ionized in dilute aqueous solution, are treated under tension with an aqueous solution of mercuric chloride, whereby the strength of the filaments is increased.  The filaments are preferably stretched to about 350 per cent of their original lenth, while undergoing treatment with the mercuric chloride solution, preferably at a temperature of 70-80 DEG  C. and preferably in the presence of hydrochloric acid. In the example filaments formed by extruding an aged solution of groundnut protein in an aqueous solution of sodium hydroxide into an aqueous sulphuric acid-sodium sulphate coagulating bath in known manner are rendered insoluble by treatment in a saturated sodium chloride solution containing formaldehyde, hydrochloric acid and sodium sulphide.  The filaments are then washed free from acid and dried at 110 DEG  C.  The insolubilized tow thus obtained is then stretched for about 30 minutes to a point just short of breakage in a bath consisting of a 3 per cent solution of mercuric chloride in 0.1 normal aqueous hydrochloric acid at 70 DEG  C.  The tow, which may now be 350-450 per cent of its original length, is then washed in running water and dried at 108 DEG  C.  The thus insolubilized filaments are increased in wet strength by about 60 per cent and in elongation at break when dry by about 200 per cent.  The elongation at break of the wet filaments is decreased by 50 per cent. Specifications 533,952 and 639,342 are referred to.

Title: Fluid actuated vibration generators
IPC: B06B1/18
Filed: 1973-02-12
Abstract: 1382764 Hydraulic reciprocating motors POCLAIN 12 Feb 1973 [24 Feb 1972] 6719/73 Heading F1A A fluid operated motor system for reciprocating a load 6 comprises a piston 2 slidable in a cylinder and defining therewith a working chamber 5, and a rotary or sliding distributing valve 13 driven by a fluid actuated rotary motor 18 and operable to connect the working chamber 5 alternately to a pressure supply 10 and a reservoir 9. The pressure supply 10 may be, as shown, a pump or alternatively a pressure accumulator (236). The output from the pump 10 also provides, via a line 12, 19, the supply for driving the motor 18 and for returning the piston 2 on changeover of the valve 13. A fixed or adjustable restriction 21 is disposed in the line 12 to control the speed of the motor 18. Fluid exhausting from the motor 18 is maintained at a certain pressure by a valve 22, this pressure being in communication through lines 23, 25 with the working chamber 5 and the inlet to the motor 18. Non-return valves 24, 26 in the lines 23, 25 operate to prevent the occurrence of very high or low-pressure in the chamber 5 when, during changeover, the valve 13 isolates the chamber 5 from both the pump 10 and the reservoir 9. The return motion of the piston may be effected by a spring (106), Fig. 7 (not shown), instead of by fluid-pressure.

The amount of the boron compound is preferably 0,02 to 0,05% by weight.  The motor fuel consists essentially of one or more hydrocarbon base stocks such as catalytic distillate, motor polymer, alkylate, catalytic reformate, isomerate or naphthas, containing from 1/2 to 6 ml. per gallon of tetraethyl lead and a scavenging agent. Antioxidants, stabilizers, solvent oils, dyes, boron compounds and phosphorus compounds may also be present. Examples describe gasoline compositions in which the additive is a borated 2-heptadecenyl-4,4-bis(hydroxymethyl) oxazoline or such a compound treated with acetic, phosphoric, oxalic, boric or hydrochloric acid, or a borated 2-heptadecenyl-4-methyl-4-hydroxymethyl oxazoline.ALSO:The invention comprises boron-containing oxazoline compounds of the general formula <FORM:0884730/IV (b)/1> in which Rx represents an aliphatic hydrocarbon radical containing 7 to 19 carbon atoms, n is 1, 2 or 3 and Rz represents hydrogen or an alkyl radical containing 1 to 3 carbon atoms.  The novel compounds may be made by reacting boric acid or boric oxide with a substituted oxazoline compound of the formula <FORM:0884730/IV (b)/2> wherein Ry represents -(CH2)nOH in which n is 1, 2 or 3 and R2 represents the same as Ry wherein X represents hydrogen or <FORM:0884730/IV (b)/3> or of the general formula <FORM:0884730/IV (b)/4> or represents hydrogen or an alkyl radical having 1 to 3 carbon atoms.  Water may be removed from the reaction mixture as it is formed, preferably by azeotropic distillation. Examples describe the reaction of 2-heptadecenyl-4,4-bis (hydroxymethyl) oxazoline with boric acid, and 2-heptadecenyl-4-methyl-4-hydroxymethyl oxazoline with boric acid. The products may be used as gasoline additives.  The borated oxazoline compounds may be treated with a non-oxidizing acid, such as boric, phosphoric, hydrochloric, acetic or oxalic acid or anhydride or mixtures thereof, in an amount such that the product has a pH of from 3.0 to 6.0.  The products, which are improved gasoline additives, are believed to be salts in which the acid is coordinated with the nitrogen of the oxazoline ring.
